I\u2019m Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for everyone who enjoys going out under the stars. \u2014 David Nagler Question show reminder.    2 Full Moons! May 1 - Full Moon \u2014 Carbon Star RY Mon best in evening May 2 - Alpha CVn Colourful Double May 3 - Antares 0.5-degrees N of Moon May 4 - Carbon Star X CnC best in evening May 6 - Eta Aquaria Meteors best in predawn skies but 3\/4 Moon interferes May 7 - Markarian\u2019s Chain well placed  Key Details of Markarian's Chain: Location: Situated in the constellation Virgo, between the stars Denebola and Vindemiatrix, part of the larger Virgo Cluster. Key Members: The chain is anchored by the large elliptical galaxies M84 and M86. Other notable members include NGC 4477, NGC 4473, NGC 4461, NGC 4458, and NGC 4438. Observation: The brightest members are visible in small telescopes, but it is a popular target for astrophotography in the spring, often requiring a wide field of view to capture the entire string. Interaction: While some galaxies are randomly aligned, at least seven members share a common physical motion. The pair NGC 4438 and NGC 4435, known as "The Eyes," are actively interacting and distorting one another. May 8 - 2 Shadows on Jupiter Ganymede & Europa 8:44pm EDT Eastern North America May 9 - Last Quarter Moon \u2014 NGC 4147 well placed May 10 - Lunar Curtis X visible May 11 - NGC 4038\/4039 well placed Key Facts About NGC 4038\/4039: Location: Constellation Corvus, the Crow. Distance: Generally estimated between and million light-years. Other Names: Caldwell 60\/Caldwell 61, the Antennae Galaxies, NGC 4038\/4039. Discovery: Found by William Herschel in 1785. Interaction Type: Colliding\/Merging galaxies. Appearance: The collision produces long tidal tails of stars, gas, and dust resembling insect antennae May 12 - Mare Orientale May 13 - NGC 5634 well placed May 15 - Ganymede & Europa shadows visible on Jupiter 11:19 pm EDT May 16 - New Moon but Old crescent in east before Sunrise today. May 18 - Venus 3-degrees S of Moon May 19 - Long period star X Oph at max 11:30pm May 20 - Jupiter 3-degrees S of Moon - Not here May 22 - Ganymede & Europa shadows visible on Jupiter 11:54 PM EDT WEST Fav. May 23 - Callisto & Io discs visible on Jupiter 10:15pm May 25 - Lunar Straight Wall visible also Longomontanus Ray May 26 - Jewelled Handle This is a monthly lunar phenomenon occurring around the first quarter moon (approx. 10\u201311 days after new moon). It appears as a bright, illuminated arc formed by sunlight hitting the peaks of the Montes Jura mountain range, which separates the dark night side from the bright day side, making it look like a handle attached to the moon May 29 - Asteroid Amphitrite at opposition Mag. 9.5 29 Amphitrite is one of the largest S-type asteroids in the Main Belt, orbiting the Sun between Mars and Jupiter. Discovered on March 1, 1854, by Albert Marth, it was the only asteroid he ever found and is named after the Greek sea goddess Amphitrite, wife of Poseidon. May 30 - Asteroid Lutetia at Opposition Mag. 9.8 21 Lutetia is a large, irregularly shaped asteroid in the main asteroid belt, measuring approximately 120 kilometers along its longest axis. It is highly significant to astronomers as a "survivor" or planetesimal from the early formation of the Solar System, roughly 4.5 billion years ago.
